Class Histogram3DCreator
java.lang.Object
net.sourceforge.jiu.ops.Operation
net.sourceforge.jiu.color.analysis.Histogram3DCreator
This class creates three-dimensional histograms for images with integer samples.
Only
IntegerImage
is supported.
Existing histogram objects can be given to this operation to be reused.
Note: Before JIU 0.10.0 there was a single HistogramCreator class.

- 0.10.0

Method Details

count
Static convenience method to count the number of colors in any three channelIntegerImage
object.- Parameters:
image
- the IntegerImage whose number of used colors is to be determined- Returns:
- the number of colors or null on failure (image does not have three channels, etc.)
- Since:
- 0.15.0
-
createHistogramIfNecessary
private void createHistogramIfNecessary() -
getHistogram
Returns the histogram initialized in this operation. -
process
Description copied from class:Operation
This method does the actual work of the operation. It must be called after all parameters have been given to the operation object.- Overrides:
process
in classOperation
- Throws:
MissingParameterException
- if any mandatory parameter was not given to the operationWrongParameterException
- if at least one of the input parameters was not initialized appropriately (values out of the valid interval, etc.)
-
setHistogram3D
Sets the histogram object to be reused for this operation. If this method is not called, a new histogram will be created.- Parameters:
histogram
- the histogram object to be used in this operation
-
setImage
The image for which a histogram will be initialized. Simply callssetImage(IntegerImage, int, int, int)
with 0, 1 and 2 as parameters.- Parameters:
newImage
- the image for the histogram initialization
-
setImage
public void setImage(IntegerImage newImage, int channelIndex1, int channelIndex2, int channelIndex3) The image for which a histogram will be initialized. Simply callssetImage(IntegerImage, int, int, int)
with 0, 1 and 2 as parameters.- Parameters:
newImage
